Found while verifying #367.

Consider the following Java enum:

package b;
public enum MyEnum {
	VAL1, VAL2, VAL3;
}

the following Java class:

package b;
public class Utility {
	public static void doSomething(MyEnum enumValue) {
	}
}

and the following Groovy class:

package b 

class Test4 { 
	void doSomething() { 
		Utility.doSom|
	} 
}

Consider these options in Java | Editor | Content assist:

• Completion overwrites CHECKED
• Use static imports UNCHECKED
• Fill method arguments and show guessed arguments CHECKED
• Insert best guessed arguments CHECKED

Invoke code assist at "|": you'll get Utility.doSomething(VAL3) (VAL3 highlighted) and then choose VAL1. The result is: Utility.doSomething(MyEnum.VAL3VAL1).

If "Use static imports" is CHECKED, the result, instead, is: Utility.doSomething(VAL3VAL1) (the added static import is correct, though).

The problem doesn't happen if you check "Completion inserts" instead of "Completion overwrites".
